Two tuning forks are labeled Q and R and have different frequencies. Tuning fork Q has a frequency of 270 Hz and tuning fork R has a frequency of 540 Hz. Both tuning forks are struck at the same time on opposite sides of a physics lab to make sound waves. Which of the sounds, if either, will move faster through the air?

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

Hahahah jsu’s hsjshshsh. shjshshshsh.

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
